Voltage comparing circuit
专利汇可以提供Voltage comparing circuit专利检索，专利查询，专利分析的服务。并且PURPOSE: To operate a comparing circuit at a high speed by accumulating the charge proportional to the offset voltage corresponding to the difference between the threshold voltages of inverter circuits.
CONSTITUTION: The charge proportional to the offset voltage generated by the difference between the threshold voltages of the inverter circuits constituting a flip-flop circuit is accumulated and utilized to reduce the effect of offset voltage. Switches S
1 -S
7 are subjected to ON/OFF control through a predetermined control signal and, at the point of time when a first inverter consisting of a first PMOS transistor and a first NMOS transistor and a second inverter consisting of a second PMOS transistor and a second NMOS transistor are in a self-bias state, the voltage proportional to the charge accumulated in a capacitor C
1 is added to either one of an input signal V
1 and a reference signal VR. By this constitution, a comparing circuit can be operated at a high speed.
